GLOBE-MANIPULATOR.

Specification of Letters Patent.

Patented Oct. 29, 1907.

Application filed February 15, 1907. Serial No. 357,470.

` distance from the operator with aview of screwing them into theirsockets or removing them therefrom.

The apparatus is so constructed that the clasp which engages the bulbmay be first set and locked to its handle at any angle desired, and maybe rotated by means -independent of the handle after being thus set andlocked. ln this way the screwing and unscrewing manipulation is greatlyfacilitated and any breakage of the bulb, owing to any uncontrolledmovement after being released from its socket, is prevented.

In the accompanying drawing: Figure 1 is a side view, partly in section,of my improved globe manipulator; Fig. 2 is a detail longitudinalsection of the clasp and adjoining parts; Fig. 3 a top view of theclasp, and Fig. -fl a detail longitudinal section of thebrush-attachment.

To the upper end of a tubular hand-rod 10 is rigidly aflixed a plate or`trame 11, shown to be made of segmental form. Over one face of plate11, turns on a lixed pivot 12, a. two-arm lever 13, provided at one endwith a tubular stem 14, and at the other end with a bearing 15. Thisbearing receives a shait 16, rotatably held thereto by a set screw 17that passes through the bearing and engages a circumferential groove ofthe shaft. Upon shalt 1.6 there is removably mounted by screw 18, aclasp 19 adapted to grasp an electric light bulb 20. Clasp 19 ispreferably composed ol a number of resilient lingers 21, which arepadded at their upper ends as at 22. Through tubular stem 14 extends aspring-influenced locking pin 23, adapted to engage either one of anumber of circumferential perforations or indentations 2-/l of plate ll.By the means described, lever 13, and consequently clasp 19, may befreely turned on pivot 12 and locked at any desired angle to rod 10. Inthis way the device may be set to readily engage bulbs 20, mounted atvarious angles to the operator.

Through the rod 10 extends a spindle 25 carrying a handle 26 at itslower end, and a bevel gear wheel 27 at its upper end, such wheel beingaccommodated by a slot 2S of plate 11. Wheel 27 intergears with a wheel29 turning on pivot 12, and separated from lever 13 by the interveningplate 11. Wheel 29, in turn, engages a bevel gear wheel 30 fast on shaft16 of clasp 19. By rotating lever 13 on its pivot 12, such lever will bemade to swing over the face of plate 11, and so revolve clasp 1.9 as toset it at whatever angle desired to rod 10. During such motion of thelever, wheel 30 will travel along wheel 29, and remain in permanentengagement therewith, at whatever 'final position may be selected forthe clasp. It will thus be seen that after the clasp has been set andlocked by lever 13 and pin 23, in the manner described, and has beenprojected over a bulb 20, it may be axially rotated, to turn the latterin either direction without turning hand rod 10, motion beingtransmitted from handle 26 to clasp 19, by spindle 25 and wheels 27, 29and 30.

In order to provide a support for the tip of bulb 20, and to obtainmeans for contracting the fingers 2l around the latter, there iscentered in clasp 19, a plate 01 cap 31, cushioned as at 32. Cap 31 ismovably suspended within the clasp by means of arms 33 pivoted at theirinner ends to the cap, and projecting with their headed outer endsthrough perforations of fingers 21. Ii clasp 19 is projected over a bulb20, cap 3l will thus form a firm bearing or support for the bulb, whichconsiderably facilitates the manipulation of the device. The capmoreover provides means for contracting the fingers 21 around the bulbin case an unusually firm grasp is desired. To this effect a string 34extends from cap 31 through shaft 16 and through eyes 35, 36 of pivot 12and rod 10 respectively, to the hand of the operator, A pull on thisstring will contract arms 33 and produce the desired contraction offingers 21 and the consequent firmer grip on the bulb.

Clasp 19 may be removed from shaft 16 and replaced by a clasp 37provided with brushes or similar cleaning or polishing devices 38 on itsinner face (Fig. 4). This clasp 37 is fitted to the apparatus wheneverinaccessible bulbs are to be cleaned or polished.

I claim:

1. A device of the character described, comprising a hollow hand rod, aplate carried thereby, a lever rotatable over the plate, means forlocking the lever to the plate at different angles, an axially rotatableclasp secured to the lever, a first gear wheel carried by the clasp, asecond gear wheel along which the first gear wheel is movable, a spindlerotatable within the rod, and means for operatively connecting saidspindle to the second gear wheel, substantially as specified.

2. A device of the character described, comprising a rod, a claspcarried thereby, a plate movable within the clasp, and means forconnectingsaid plate with the clasp, substantially as specied.

3. A device of the character described, comprising a rod, a perforatedclasp carried thereby, a plate movable within the clasp, and headed armspivoted to the -plate and engaging the clasp-perforations, substantiallyas specitied.

-l. In an instrument for applying or removing electric lamp bulbs, thecombination of two members adjustable to different angles in respect toone another, a shaft carried by each of said members, means for rotatingone of said shafts, interposed bevel gears whereby movement can betransmitted from one shaft to the other in any position ot' adjustmentof the latter, and bulb-clamping devices carried by the latter shaft.

5. In an instrument for applying or removing electric light bulbs, thecombination of two members adjustable to different angles in respect toone another and each carrying a shaft, means for locking said members intheir different postions of angular adjustment, means for rotating oneof said shafts, means for transmitting rotative movement from said shaftto the other in any position of adjustment of the latter, andbulb-clamping devices carried by the latter shaft. A

6. In an instrument for applying or removing electric light bulbs, thecombination oftwo members adjustable to different angles in respect toone another, a shaft carried by each member, means for rotatingthe/shaft of one member, means for imparting rotative movement from saidshaft to that carried by the other member, a bulb-clamping device on thelatter shaft, and means mounted upon said shaft-carrying member forexpanding and contracting said clamping device. i

7. In an' instrument for applying or removing electric lamp bulbs, thecombination. of two members adjustable to different angles in respect toone another and each carrying a shaft, means for rotating one of saidshaftsy means for imparting rotative movement' therefrom to the othershaft in any of its positions of adjustment, and a bulb-clamping devicecarried by the latter shaft.
